Abstract:
The purpose of this study is to compare regional impacts of woody biomass utilization between for wood chip for fuel (WC) and high value-added products called Master batch of Cellulose Nanofiber (MB) in Maniwa, Japan. Concretely, we examined the impact of regional economic structure, the employment opportunities by means of Input-Output (I/O) model, and amount of Greenhouse Gas emissions was also estimated using 3-EID data and the result of I/O analysis. For this study, three different situations were described: WC scenario, MB scenario, and Business as usual (BAU) scenario. As a result, demand and supply structure in the economy of Maniwa has changed relatively little in WC scenario compared to MB scenario. And, 103 employed people can be increased through the implementation of MB scenario, while only 7 employed people can be generated under the WC scenario. Under the MB scenario, gross demands per a GHG emission were decreased by 0.23%, whereas the WC scenario was increased by 0.1% compared to BAU scenario. On the basis of results, in-depth analysis for effective utilization of woody biomass toward economically and environmentally sound development in rural regions is needed and we will leave it as a future task.
